National Aeronautics and Space Administrion

Since its inception in 1958, NASA has accomplished many great scientific and technological feats in air and space. NASA technology also has been adapted for many nonaerospace uses by the private sector. NASA remains a leading force in scientific research and in stimulating public interest in aerospace exploration, as well as science and technology in general. Perhaps more importantly, our exploration of space has taught us to view Earth, ourselves, and the universe in a new way. While the tremendous technical and scientific accomplishments of NASA demonstrate vividly that humans can achieve previously inconceivable feats, we also are humbled by the realization that Earth is just a tiny "blue marble" in the cosmos. Check out our "Thinking About NASA History" folder online as an introduction to how history can help you.

Binary Star Map

"Scientists said yesterday (February 22, 2021) that they’ve now created a 3D plot of more than a million pairs of binary stars, that is, double stars orbiting a common center of gravity. Astronomer Kareem El-Badry of UC Berkeley created the new plot, which wildly improves upon previous data that revealed just 200 double-star pairs."
